青藏高原典型纹层湖泊孢粉分析数据集（350-2006）

本数据集来源于论文：Cui, A.N., Lu, H.Y., Liu, X.Q., Shen, C.M., Xu, D.K., Xu, B.Q., Wu, N.Q., 2021. Tibetan Plateau precipitation modulated by the periodically coupled westerlies and Asian monsoon. Geophysical Research Letters, 48, e2020GL091543. DOI: 10.1029/2020GL091543. 作者利用青藏高原北部库赛湖年纹层沉积具有准确定年的优势，高分辨率分析（~5年分辨率）、鉴定了过去1656年（公元350年到公元2006年止）以来库赛湖周边地区植物孢粉种类的变化，并基于库赛湖及其周边800 km范围内的735个现代表土孢粉组合及气象插值数据，建立了高精度的孢粉-年降水转换函数，定量重建了过去1656年降水和年均温变化。本数据集为研究青藏高原过去气候变化规律及预测未来气候变化趋势提供参考。

This dataset is derived from the paper: Cui, A.N., Lu, H.Y., Liu, X.Q., Shen, C.M., Xu, D.K., Xu, B.Q., Wu, N.Q., 2021. Tibetan Plateau precipitation modulated by the periodically coupled westerlies and Asian monsoon. Geophysical Research Letters, 48, e2020GL091543. DOI: 10.1029/2020GL091543.
The authors leveraged the advantage of accurately datable annual laminar sediments from Lake Kusai in the northern Tibetan Plateau, performed high-resolution (~5-year resolution) analyses, and identified temporal changes in plant pollen taxa in the vicinity of Lake Kusai over the past 1656 years (from 350 CE to 2006 CE). Furthermore, based on 735 modern surface pollen assemblages and meteorological interpolation data within 800 km around Lake Kusai and its surrounding regions, they established a high-precision pollen-annual precipitation transfer function, and quantitatively reconstructed the variations in annual precipitation and mean annual temperature over the past 1656 years. This dataset serves as a reference for researching the patterns of past climate change on the Tibetan Plateau and predicting future climate change trends.
